Q

what are some developmental considerations for the skin?

A

infants have weak mucous membranes hat are easily injured

kids younger than 2 have thinner and weaker skin than adults

the structure of the skin changes with age leading to thin easily damaged skin

circulation and collagen formation are impaired leading the decreased elasticity

8
Q

what is hemostasis?

A

it occurs immediately post initial injury and involves blood vessels which constrict and begin clotting.
exudate is formed causing swelling and pain.
platelets stimulate other cells to migrate to the site of injury for further phases of healing

9
Q

what is the inflammatory phase?

A

this occurs after hemostasis and lasts 2-3 days. WBC’s (leukocytes and macrophages) move to the wound site to ingest the remaining debris and to attract fibroblasts to fill in the wound

Q

what is the proliferation phase?

A

it lasts for several weeks and is when new tissue is built to fill in the wound via the fibroblasts. capillaries grow across the wound and a thin layer of epithelial cells form. granulation tissue forms the foundation for scar tissue.

16
Q

what are the stages of a pressure injury?

A

stage 1: non-blanchable erythema on intact skin
stage 2: partial-thickness skin loss with exposed dermis
stage 3: full-thickness skin loss, doesn’t involve under lying tissues/fascia
stage 4: full-thickness skin and tissue loss

un-stagable: obscured full-thickness skin and tissue loss
deep tissue pressure injury: persistent, non-blanchable deep red/maroon/purple discoloration

17
Q

how do you measure a pressure injury?

A

obtain size of wound
depth of the wound
look for presence or undermining, tunneling or sinus tract

use q-tips, rulers and photos for possible developmental changes

18
Q

explain: how to clean a pressure injury/wound

A

clean wound with every dressing change
use a new gauze for each wipe, cleaning from top-bottom or from center-outside
use 0.9% NSL to irrigate and clean site
once wound is cleaned, dry with gauze in same manner above
document and report and drainage or necrotic tissue

19
Q

what are the different types of wound drainage?

A

serous: clear, serous portion of blood from membranes
sanguineous: containing or mixed with blood
serosanguineous: mixture of RBCs and serum
purulent: comprised of WBCs, dead tissues, debris and dead/live bacteria

20
Q

assessing a wound includes

A

inspection: sight and smell
palpation: appearance, drainage, and pain

sutures, drains or tubes and any manifestation of complications

21
Q

what are the indicators for presence of an infection

A

swelling
deep red colored
radiating warmth/ hot to the touch
drainage is increased and possibly purulent
foul odor may be present
wound edges may be seperated with dehiscence present

22
Q

what is the purpose of wound dressings?

A

provide physical, psychological and aesthetic comfort
prevent, eliminate or control infections
absorb drainage
maintain moisture balance of wound
protect the wound from further injury
protect the surrounding tissues
stimulate and/or optimize healing response
consider ease of use and cost-effectiveness
debride os appropriate

23
Q

what are the types of wound dressings?

A

telfa pads
gauze dressings
transparent dressings (tegaderm)

24
Q

what are the different types of bandages?

A

roller bandages
circular turn
spiral turn
figure-of-eight turn

25
Q

what are the different types of binders?

A

slings
abdominal binders
chest binders
t-binders

26
Q

what are the 2 types of drainage systems and their drains?

A

open systems: penrose drain

closed systems: jackson-pratt drain, hemovac drain, and wound vac

27
Q

what are penrose drains?

A

they are passive drainage tubes that are soft, flexible, and made of rubber. they are used as surgical drains to prevent buildup of fluid in the surgical site.

28
Q

what are jackson-pratt drains?

A

they are a tube attached to a bulb that uses suction to pull continuous fluids from within the surgical site/cavity.

document the color and characteristics of fluid.
emptied every 4-6 hours generally.

increases in bright red drainage indicates possible internal bleeds.

29
Q

what are the topics for at home health care teaching?

A
supplies required
infection prevention
wound healing and what to expect
appearance of the skin/recent chages
activity/mobility
nutrition 
pain
elimination
30
Q

what are nursing assessments for pressure injuries?

A
risk assessments
mobility level
nutritional status
moisture present or incontinence
appearance of preexisting pressure injuries
pain assessments
31
Q

what are the factors affecting responsiveness to hot or cold treatments?

A

method and duration of application
temperature of the hot or cold applications
patients age and physical condition
amount of body surface covered by application

32
Q

what are the effects of applying heat to an injury?

A
dilates peripheral blood vessels
increases tissue metabolism
reduces blood viscosity and increases permeability
reduces muscle tension
helps relieve pain
33
Q

what are the effects of applying cold to an injury?

A

constricts peripheral blood vessels
reduces muscle spasms
promotes comfort

34
Q

what devices can be used to apply heat therapy?

A
hot water bags
electric blankets
aquathermia pads
hot packs
warm/moist compresses
sitz baths
warm soaks
35
Q

what devices can be used to apply cold therapy?

A

ice bags
cold packs
hypothermia blankets
cold compresses to apply moist cold

20 mins on and 20 mins off
use a barrier between skin and cold item

36
Q

what are some causes of skin alterations?

A

being very thin or obese predisposes one to skin injury

excessive perspiration during an illness predisposes to skin break down

jaundice causes yellow itchy skin

diseases of the skin (eczema and psoriasis) that can cause lesions

37
Q

what are the 3-types of wound healing?

A

first-intention: an open wound is closed surgically with sutures or staples as soon as possible

second-intention: would is kept clean and open to allow tissue to repair self and close on own

third-intention: the wound is left open to allow infection to clear before later being closed surgically with sutures of staples

38
Q

what is the maturation phase of healing?

A

it is the final stage which starts 3 weeks post initial injury and can continue healing for months or years

collagen is remodeled with new collagen being deposited

scar becomes a flat, thing white line

39
Q

what are hemovac drains vs wound vac drains?

A

hemovac: tube with holes inserted in the wound with an accordion press that creates suction
vac: a foam dressing inside the wound, covered by a transparent file with suction via a vacuum machine that physically pulls out drainage to improve granulation and wound healing
